Linear regressions with endogeneity are widely used to estimate causal effects. This paper studies a statistical framework that has two common issues, endogeneity of the regressors, and heteroskedasticity that is allowed to depend on endogenous regre

Bosonic bunching is a term used to describe the well-known tendency of bosons to bunch together, and which differentiates their behaviour from that of fermions or classical particles. However, in some situations perfectly indistinguishable bosons may

A Bernoulli factory is a randomness manipulation routine that takes as input a Bernoulli random variable, outputting another Bernoulli variable whose bias is a function of the input bias. Recently proposed quantum-to-quantum Bernoulli factory schemes
